The spring-loaded arm and adjustable magnetic pad give the MagSpring clamp its name, but fast clamping and one-handed operation set the clamp apart from other sliding bar clamps.
Clamping is as easy as pulling the spring-loaded arm back, positioning the clamp, and releasing the arm. As pressure is applied by the spring, the adjustable magnetic pad conforms to round, flat, or square metal surfaces, maximizing the gripping surface area. Tightening the T-handle then fully secures the clamp.
Strong Hand Tools sells four different models of the MagSpring clamp that differ in capacity and throat depth. The smallest model has a 3-1/2″ capacity with a 2-1/2″ deep throat, and the largest has a 5-1/2″ capacity with a 3-1/4″ deep throat.
